A mobile phone carrier charges an extra fee if a customer uses more than 500 minutes each month. Tom has already used 230 minutes this month. Which inequality can be used to determine how many more minutes Tom can use this month without going over the 500-minute limit?

Respuesta :

Let x = the minutes that Tom has remaining before exceeding 500 minutes.

Because he has already used 230 minutes, the total minutes he has is
x + 230
We want this total to be less than or equal to 500 minutes.
Therefore
x + 230 ≤ 500

Answer:  x + 230 ≤ 500

Answer:

D

Step-by-step explanation:

230+m<_ 500
